Benefits of technology

The patent describes a photographing apparatus and method that can measure and create a 3D shape of an object using a fish eye lens and multiple light emitters. The light emitters are placed around the lens at different angles to capture the object's shape. The apparatus includes a housing with the fish eye lens and the light emitters. The method involves controlling the light emitters to emit light at different times and analyzing the reflected light to calculate the distance of the object from the light emitters. The apparatus can also extract color information from the reflected light. The technical effects of this invention include the ability to capture a wide-area 3D shape of an object and improve image quality through the use of infrared light.

Problems solved by technology

However, the photographing apparatus according to the related art may only measure a 3D image of an object that is present within a narrow area at one time.

Abstract

Provided is a photographing apparatus which includes: a fish eye lens; a plurality of light emitters disposed around the fish eye lens and configured to emit light at different angles with respect to an optical axis of the fish eye lens; and an image sensor configured to receive the light emitted from the plurality of light emitters and reflected by at least one object, and convert the light into an electric signal.

Description

CROSS-REFERENCE TO THE RELATED APPLICATION[0001]This application claims priority from Korean Patent Application No. 10-2015-0031115, filed on Mar. 5, 2015, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.BACKGROUND[0002]1. Field[0003]Apparatuses and methods consistent with exemplary embodiments relate to a photographing apparatus and method, and more particularly, to a photographing apparatus and method by which depth information about an object may be acquired throughout a wide area at one time.[0004]2. Description of the Related Art[0005]Methods of measuring a distance to an object by using light have been widely used. The methods of measuring a distance by using light may be classified as a triangulation method, a time of flight (TOF) method, and a method using a phase-shift.[0006]The triangulation method is a method of measuring a distance by using triangulation, and the TOF method is a method of calculating...
